Sep 1, 2025September 2025 (ZeitOnline/vivi) delivered meaningful business value through streamlined image workflows, richer asset metadata, and stronger test/deployment foundations. The month combined feature work with reliability improvements to enable faster publishing and scalable asset management. Key features delivered: - WCM-1073: Image editing workflow improvements — publish/open after new image upload; update translations; simplified opening/editing flow; no AJAX; German naming refined. - WCM-1107: Expanded image metadata handling — rename to embedded metadata; read/flatten embedded data; parse ICC color profiles; groundwork for multiple metadata types; translations updated. - WCM-978: Bulk edit metadata — bulk editing for image uploads; preserve translations with span; move script into resources; improved bulk edit UI/flow. - WCM-1097/SQL-based testing — activate connectors across packages; migrate tests to SQL-based approach; add SQL tests for zeit.find. - WCM-1123/1125: Image upload flow and lifecycle fixes — fix JS flow, add break statements where needed, implement upload synchronization; retry logic and cleanup for abandoned temporary images. Major bugs fixed: - WCM-1001: Stay within your borders memo field (validation/UX constraint). - WCM-1089: Filename fallback in metadata (use filename when title missing). - WCM-978: Flaky test teardown and UI translation gaps; bulk edit button style corrected. - WCM-1123: Correct JavaScript flow and upload behavior; ensure proper form usage; preserve previous behavior where appropriate. - WCM-1125: Image upload lifecycle improvements; remove abandoned temporary images; index updates for last_updated. Overall impact and accomplishments: - Faster publishing and editing workflows for images, improved asset metadata capabilities, and stronger test coverage. The changes reduce manual validation, increase data richness, and provide a solid foundation for future metadata types and connectors across packages. Technologies/skills demonstrated: - Testing infrastructure enhancements (test data layers, SQL-based testing, translations on tests). - Metadata parsing and data modeling (embedded metadata, flattening, ICC profiles, mixed-type lists). - Frontend/JS refactoring and reliability (imageupload refactor, synchronous scripts, robust flow). - CI/CD and tooling improvements (ESLint, pre-commit tooling, Node version updates, translation maintenance).

Mar 1, 2025March 2025 performance summary for ZeitOnline/vivi: major overhaul of VG Wort integration and scheduling, delivering reliable data handling, safer publish/retract flows, and improved developer tooling. Key features delivered include WCM-525 VG Wort integration enhancements (nullable date support, SQL connector, internal DB reads, and clearer SQL/statements), WCM-758: added VG Wort data columns, and WCM-252: timeout on search SQL to prevent long-running queries. WCM-753 provides a CLI to run individual publish tasks and services. WCM-694 introduces a cron-based scheduling model (migrating from Celery, moving retract to CLI, and adding SQL layer support for scheduled cronjobs) plus date_last_retracted with indexing and enhanced safety checks to prevent republish after retract. Additional work includes translations updates, test suite modernization, and maintenance improvements (replacing deprecated logging warn). A bug fix corrects VG Wort metrics method usage to ensure accurate metrics.
